Corningware: Removing Tough Stains

[peterh770]

I purchased a Corningware coffee percolator at an estate sale last weekend. In the bottom of the pot is some really, Really, REALLY burnt on coffee. It has obviously been scrubbed, and the burnt surface is smooth, but is there a way to remove tough burned on foods and liquids from Corningware?

Chlorine

I would try chlorine bleach, if this does not work, fina a Miele dealer that carries cleaning producst and get some SIDOL. It is promoted by them to clean smoothtop (Ceran) cooktops and stainless steel and it works better then any "soft Scrub" material I have ever used. In the equipment class there is a cleaning lab and SIDOL always outcleass other products. I suspect your issue is a pigment stain and chloring bleach should work.

2 things you may try.

1)crushed ice and salt.fill it 1/4 full with crushed ice and 3tbsp of salt.Shake the pot swirling the mixture.The coarseness takes the cooked on coffee off

2)Chlorox spill proof bleach.I don't know what they added but there's some extra ingredient in this that realy excells its ability to whiten whites.I use it in my porcelain kitchen sink(1C to 5 gal.hot tap water) and it keeps that old clucker gleaming white!Use the HEtype and put 1/8C in a full pot and let it perk with all the pieces.I think you'll be impressed!

3)CLR This gem realy removes stains and build up caused by calcium,lyme and rust.Use 1/2C and perk away!

I'm a firm believer in lye-based oven cleaner like Easy-off.

After that try boiling with Cascade or equivalent.

Easy Off will get it out! Just let it sit for a good while.

Second the lye suggestion. You could even use dry lye crystals and some water. Just make sure you add the water first, then slowly add the lye crystals with stirring. It will heat up as the lye dissolves. Let it sit overnight and then rinse down the drain with plenty of cold water.

Oven cleaner...I third that!!

I collect electric Corning percs and I have seen some of the most disgusting pots! I have had excellent results by boiling a full pot of water. Empty it out and while still hot spray it with oven cleaner. Let this set for an hour or two. I then fill it with water, again, and put in about 1 teaspoon of dishwasher powder detergent. Perc this again then let it just cool of then pour it out and rinse the pot. It should look like new. The only time that I have had a problem is when someone previously scoured the pot with Brillo.

Good luck and let us know how it comes out
